Written by Roald Dahl, You Only Live Twice may just be the single greatest Bond film of all time (it's also famous for the scene where a bevy of Japanese agents are mesmerized by Sean Connery's manly chest-mane. Yes, a hot tub is involved). John Barry's work is superlative as always, including the Nancy Sinatra-sung theme song. Barry and other Bond composers would reuse the instrumental motif to this number every time James Bond came across an island oasis or female-strewn beach scene.
